Military Technology

In addition, our other smart bionic artificial organs and tissues are also being actively promoted as part of the smart bionic organ project, and have made very good progress. When we have results, we will promptly Report to everyone.

Wu Hao added, and then continued: "In addition to this kind of intelligent bionic artificial organs, we are also actively researching bio-3D printing organ tissue technology, and cloning and cultivation technology of human cell tissues. At present, we can already realize some small Cell cloning printing and transplantation technology for tissues and organs.”

At this point, Wu Hao paused and waited for everyone in the audience to calm down and concentrate on looking at him before he continued.

These two technologies seem to be two independent technical categories, but we have magically combined them. In order to print an organ tissue that can be transplanted to an injured or sick patient, we must first collect somatic cells from the patient.

This is because the somatic cells extracted from the patient are cloned and cultured, and then printed into organ tissue and transplanted to the patient, there will be no rejection reaction. This is one of the biggest advantages of this technology, which means that we can clone and print artificial organs and tissues that are no different from the original ones in your body.

After these somatic cells are taken out, they will be processed and then cloned and cultivated to produce enough somatic cells. This is the raw material for biological 3D printers, which is basically equivalent to the consumables of ordinary 3D printers.

After we have the raw materials, we will next use a bio-3D printer to print. Before printing, we need to draw a diagram of the organ tissue structure of the printed part. We must first understand the structural structure of these organs and tissues, so that we can print these organs and tissues in a targeted manner. Otherwise, what is printed is a piece of waste meat.

And this gave rise to another technology, which is the ultra-fine 3D digital model of the human body. Everyone knows about the 3D digital model of the human body, and it is also understandable about the ultra-fineness, but everyone is not sure what level of ultra-fineness it reaches.

Let me tell you this, the consumables used by this biological 3D printer are somatic cells, which also means that its printing accuracy is at the cell level, so this ultra-fine 3D digital model of the human body must also be at the cell level.

To draw such a detailed 3D digital model of the human body is a huge task, which means we have to break down the human body into individual cells. The total number of cells in a normal person is about 40 trillion to 60 trillion. It is basically impossible for people to complete this work.

Hearing the number reported by Wu Hao, the audience couldn't help but exclaimed. This is almost equivalent to half a year's GDP of the country. If it were completed by others, it would probably take tens of thousands of years to complete.

Wu Hao saw the reaction below and continued with a smile: "At this time, the intervention of supercomputers can help us accomplish many things. Through a series of complex mathematical formulas and models, we can automatically generate this ultra-fine 3D digital model of the human body. Then we will continue to correct it, and we will be able to obtain a more accurate 3D digital model data of the human body.

Then, we can use this ultra-fine human body 3D digital model data to print out the required organ tissue parts. However, these printed organ tissue parts cannot be put into use immediately. Instead, they need to be continuously verified to ensure that these organs and tissues have the same physiological functions as the original ones, and can remain stable and not prone to change.

Because this project is relatively ambitious, we are currently only able to replicate and print human skin tissue, muscle tissue, including nerve tissue, various arteries and veins, including cardiac tissue.

And I am very proud to tell you that the various types of organs and tissues we have printed have been used in clinical trials, and have achieved excellent therapeutic effects.

Do you still remember a fire-fighting heroine we participated in the rescue? "

After hearing Wu Hao's words, many people in the audience began to answer. Wu Hao smiled and nodded: "Yes, it was Ms. Zou Feifei. She was burned by the fire while trying to save the passengers in the hotel. Fortunately, the firefighters arrived in time to rescue her and saved her life. However, she herself was seriously injured. Burns, disfigurement.

This made Zou Feifei very painful, and she even considered committing suicide. After we learned of her heroic deeds, we immediately contacted the other party and brought her and her mother to Anxi for treatment.

By that time, her superficial burns had healed, but severe burn scars were left, especially on her face and head. In addition to severe burns on her skin, there were also some deep muscle and nerve and blood vessel injuries, including one on her head. Eye.

So we immediately convened some domestic medical experts with rich experience in the treatment of burns, as well as some of our technical experts, to form a joint expert group to treat Zou Feifei.

After consultation and consultation, we decided to start repairing the deep muscle tissue and neurovascular tissue of Zou Feifei’s burn site first, and then repair her damaged skin and use bio-3D printing technology to give her a new face. "

When Wu Hao was introducing, the three naked-eye 3D projection screens above his head were also playing relevant images.

Wu Hao paused and looked for Shuyuan www. zhaoshuyuan． com glanced at the people in the audience, and then continued: "The entire treatment process is very complicated. We need to clean up the damaged parts of the patient first and remove the damaged muscles, nerves and blood vessel tissue.

Then, Zou Feifei's somatic cells were used to clone and cultivate 3D bio-printed tiny muscle fibers, blood vessels and nerve tissue, and then gradually transplanted them to Zou Feifei's face.

As we all know, the muscle, nerve and blood vessel network of the human face is very complex, and it is very difficult to completely repair it. This can be said to be a very large and complicated treatment project, and there is no shortcut, so we proceed step by step intelligently.

Most of the time, the patient may have to perform a recovery operation every week. After several operations, we finally completed the repair of her facial muscle, neurovascular tissue, including the nasal cartilage, eyeball muscles, and ear cartilage. etc.

After completing the basics, we begin to repair the patient’s facial skin. Under normal circumstances, there are generally three technical methods for repairing and reconstructing disfigured patients. The first is to perform surgical cosmetic reconstruction on the original basis. Through surgical intervention, people can naturally grow ideal skin. However, the effect of this kind of surgery is so poor that it has basically been abandoned. "
